I used to do that but then I started thinking of the health benefits .... fast food has none ... it would probably be healthier to eat sugar mixed with sawdust.

It's paying money to degrade your health, which you then spend money on trying to fix later in life .... it's investing in bad health and after 20 years you then spend money to try to fix the bad health and weight that you essentially paid for.

When you look at an entire lifespan, eating fast food makes you pay twice - once when you buy the food - then again after its caused bad health that you spend money on trying to fix.

It's far cheaper and probably extends your life (especially healthy life) if you just don't eat any of it.
